Descriptions
North Island: WKR, vic. Forestry Headquarters, 24.vi.81, coll. RHP, no. 42421 (TENN). South Island: PSR,19.v.82, coll. RHP, no. 43573 (TENN); PSR same date, no. 43574 (TENN).
Fruit bodies up to 50 x 2 mm, simple clubs, cylindrical, equal, uninflated, gregarious, bright yellow ("apricot yellow", "cadmium yellow") all over except stipe base. Stipe up to 17 x 1.5 mm, terete, equal, arising from a small whitish mycelial patch, pale below ("light cadmium"), concolorous to club above. Club opaque; apex rounded. Odour negligible; taste negligible.
Macro chemical reaction: FCL = negative to obscurely weakly grey-green.
Tramal hyphae of club 3-7 µm diam., hyaline to pale yellow, clamped, occasionally secondarily septate, parallel, free. Subhymenium extensive. Hymenium thickening, congested, of two elements: (a) >basidia 40-50 x 6-8 µm, clavate, refringent, multiguttulate when mature, (2)-4-sterigmate; and (b) less inflated to uninflated leptocystidial to basidiolar processes, sinuous to lobed when uninflated, more refringent with inflation.
Spores 5.9-7.0 x 4-4.5 µm (Lm = 6.45 µm), ellipsoid to ovate, smooth, thin-walled, refringent to greenish yellow under phase contrast; contents uniguttulate when mature; hilar appendix small, inconspicuous.

I have laboured over this name for years, finally pinning it to the above concept (Petersen 1979). The taxon seems to be distributed over the Southern Hemisphere, at least in temperate areas. For a more complete description see Petersen (1979) under Clavaria aurantia, a synonym used before I examined the type specimen of C. amoena.
